Rated 5 out of 5 stars
One of its features, "momentum scroll" is very funny and useful. When I browse webpages roughly, I don't have to hit SPACE key or use scroll wheel. Only I have to do that: move mouse (or my finger on the slide pad) quickly. With this addon, I'm comfortable while browsing.This review is for a previous version of the add-on (220.127.116.11).
